Well, according to the BBC they do. A survey by Which? magazine goes on to cite examples such as 'Marks and Spencer's Pasta with Tomato & Basil Chicken', Sainsbury's Thai Chicken Noodle and 'Sainsbury's Tomato & Basil Chicken'.
Excuse me? These are pasta and noodle dishes, not salads.
Most people equate 'salad' with plants (although the word 'salad' actually means 'mixture') and, therefore, I think this article is misleading.
This biased article will only serve to allow some people to normalise stuffing their faces with burgers whilst saying "it's no more fattening than salad". They'll probably go on to blame Which? or the BBC for them being overweight.
Salad vegetables are low fat. It's the other stuff you put with them, like dressings and mayonnaise that makes it fattening. Eat a proper vegetable salad and, believe me, you won't be eating a lot of fat.
My mum got it right years ago. She said that if you buy fresh food and don't live off food mixed and prepared in factories, you will have a healthier diet. Stop buying convenience foods and learn how to prepare stuff yourself. It's not difficult.
